Hybrid toxins are producedrecombinantly by a new combination of different domains of thoseproteins (see, for example, WO 02/15701). Truncated toxins, for examplea truncated Cry1Ab, are known. In the case of modified toxins, one ormore amino acids of the naturally occurring toxin are replaced. In suchamino acid replacements, preferably non-naturally present proteaserecognition sequences are inserted into the toxin, such as, for example,in the case of Cry3A055, a cathepsin-G-recognition sequence is insertedinto a Cry3A toxin (see WO 03/018810).

Examples of such toxins or transgenic plants capable of synthesisingsuch toxins are disclosed, for example, in EP-A-0 374 753, WO93/07278,WO95/34656, EP-A-0 427 529, EP-A-451 878 and WO 03/052073.

The term “locus” as used herein means fields in or on which plants aregrowing, or where seeds of cultivated plants are sown, or where seedwill be placed into the soil. It includes soil, seeds, and seedlings, aswell as established vegetation.

The term “plants” refers to all physical parts of a plant, includingseeds, seedlings, saplings, roots, tubers, stems, stalks, foliage, andfruits.

The term “plant propagation material” is understood to denote generativeparts of the plant, such as seeds, which can be used for themultiplication of the latter, and vegetative material, such as cuttingsor tubers, for example potatoes. There can be mentioned for exampleseeds (in the strict sense), roots, fruits, tubers, bulbs, rhizomes andparts of plants. Germinated plants and young plants which are to betransplanted after germination or after emergence from the soil, mayalso be mentioned. These young plants can be protected beforetransplantation by a total or partial treatment by immersion. Preferably“plant propagation material” is understood to denote seeds.

The compounds of formula I may be used in unmodified form or,preferably, together with the adjuvants conventionally employed in theart of formulation. To this end they may be conveniently formulated inknown manner to emulsifiable concentrates, coatable pastes, directlysprayable or dilutable solutions or suspensions, dilute emulsions,wettable powders, soluble powders, dusts, granulates, and alsoencapsulations e.g. in polymeric substances. As with the type of thecompositions, the methods of application, such as spraying, atomising,dusting, scattering, coating or pouring, are chosen in accordance withthe intended objectives and the prevailing circumstances. Thecompositions may also contain further adjuvants such as stabilizers,antifoams, viscosity regulators, binders or tackifiers as well asfertilizers, micronutrient donors or other formulations for obtainingspecial effects.

Suitable carriers and adjuvants, e.g. for agricultural use, can be solidor liquid and are substances useful in formulation technology, e.g.natural or regenerated mineral substances, solvents, dispersants,wetting agents, tackifiers, thickeners, binders or fertilizers. Suchcarriers are for example described in WO 97/33890.

Suspension concentrates are aqueous formulations in which finely dividedsolid particles of the active compound are suspended. Such formulationsinclude anti-settling agents and dispersing agents and may furtherinclude a wetting agent to enhance activity as well an anti-foam and acrystal growth inhibitor. In use, these concentrates are diluted inwater and normally applied as a spray to the area to be treated. Theamount of active ingredient may range from 0.5% to 95% of theconcentrate.

Wettable powders are in the form of finely divided particles whichdisperse readily in water or other liquid carriers. The particlescontain the active ingredient retained in a solid matrix. Typical solidmatrices include fuller's earth, kaolin clays, silicas and other readilywet organic or inorganic solids. Wettable powders normally contain from5% to 95% of the active ingredient plus a small amount of wetting,dispersing or emulsifying agent.

Emulsifiable concentrates are homogeneous liquid compositionsdispersible in water or other liquid and may consist entirely of theactive compound with a liquid or solid emulsifying agent, or may alsocontain a liquid carrier, such as xylene, heavy aromatic naphthas,isophorone and other non-volatile organic solvents. In use, theseconcentrates are dispersed in water or other liquid and normally appliedas a spray to the area to be treated. The amount of active ingredientmay range from 0.5% to 95% of the concentrate.

Granular formulations include both extrudates and relatively coarseparticles and are usually applied without dilution to the area in whichtreatment is required. Typical carriers for granular formulationsinclude sand, fuller's earth, attapulgite clay, bentonite clays,montmorillonite clay, vermiculite, perlite, calcium carbonate, brick,pumice, pyrophyllite, kaolin, dolomite, plaster, wood flour, ground corncobs, ground peanut hulls, sugars, sodium chloride, sodium sulphate,sodium silicate, sodium borate, magnesia, mica, iron oxide, zinc oxide,titanium oxide, antimony oxide, cryolite, gypsum, diatomaceous earth,calcium sulphate and other organic or inorganic materials which absorbor which can be coated with the active compound. Granular formulationsnormally contain 5% to 25% of active ingredients which may includesurface-active agents such as heavy aromatic naphthas, kerosene andother petroleum fractions, or vegetable oils; and/or stickers such asdextrins, glue or synthetic resins.

Dusts are free-flowing admixtures of the active ingredient with finelydivided solids such as talc, clays, flours and other organic andinorganic solids which act as dispersants and carriers.

Microcapsules are typically droplets or granules of the activeingredient enclosed in an inert porous shell which allows escape of theenclosed material to the surroundings at controlled rates. Encapsulateddroplets are typically 1 to 50 microns in diameter. The enclosed liquidtypically constitutes 50 to 95% of the weight of the capsule and mayinclude solvent in addition to the active compound. Encapsulatedgranules are generally porous granules with porous membranes sealing thegranule pore openings, retaining the active species in liquid forminside the granule pores. Granules typically range from 1 millimetre to1 centimetre and preferably 1 to 2 millimetres in diameter. Granules areformed by extrusion, agglomeration or prilling, or are naturallyoccurring. Examples of such materials are vermiculite, sintered clay,kaolin, attapulgite clay, sawdust and granular carbon. Shell or membranematerials include natural and synthetic rubbers, cellulosic materials,styrene-butadiene copolymers, polyacrylonitriles, polyacrylates,polyesters, polyamides, polyureas, polyurethanes and starch xanthates.

Other useful formulations for agrochemical applications include simplesolutions of the active ingredient in a solvent in which it iscompletely soluble at the desired concentration, such as acetone,alkylated naphthalenes, xylene and other organic solvents. Pressurisedsprayers, wherein the active ingredient is dispersed in finely-dividedform as a result of vaporisation of a low boiling dispersant solventcarrier, may also be used.

Another aspect of invention is related to the use of a compound offormula (I) or of a preferred individual compound as defined herein, ofa composition comprising at least one compound of formula (I) or atleast one preferred individual compound as above-defined, or of afungicidal or insecticidal mixture comprising at least one compound offormula (I) or at least one preferred individual compound asabove-defined, in admixture with other fungicides or insecticides asdescribed above, for controlling or preventing infestation of plants,e.g. useful plants such as crop plants, propagation material thereof,e.g. seeds, harvested crops, e.g. harvested food crops, or non-livingmaterials by insects or by phytopathogenic microorganisms, preferablyfungal organisms.

A further aspect of invention is related to a method of controlling orpreventing an infestation of plants, e.g., useful plants such as cropplants, propagation material thereof, e.g. seeds, harvested crops, e.g.,harvested food crops, or of non-living materials by insects or byphytopathogenic or spoilage microorganisms or organisms potentiallyharmful to man, especially fungal organisms, which comprises theapplication of a compound of formula (I) or of a preferred individualcompound as above-defined as active ingredient to the plants, to partsof the plants or to the locus thereof, to the propagation materialthereof, or to any part of the non-living materials.

Controlling or preventing means reducing infestation by phytopathogenicor spoilage microorganisms or organisms potentially harmful to man,especially fungal organisms, to such a level that an improvement isdemonstrated.

A preferred method of controlling or preventing an infestation of cropplants by phytopathogenic microorganisms, especially fungal organisms,or insects which comprises the application of a compound of formula (I),or an agrochemical composition which contains at least one of saidcompounds, is foliar application. The frequency of application and therate of application will depend on the risk of infestation by thecorresponding pathogen or insect. However, the compounds of formula (I)can also penetrate the plant through the roots via the soil (systemicaction) by drenching the locus of the plant with a liquid formulation,or by applying the compounds in solid form to the soil, e.g. in granularform (soil application). In crops of water rice such granulates can beapplied to the flooded rice field. The compounds of formula I may alsobe applied to seeds (coating) by impregnating the seeds or tubers eitherwith a liquid formulation of the fungicide or coating them with a solidformulation.

A formulation, e.g. a composition containing the compound of formula(I), and, if desired, a solid or liquid adjuvant or monomers forencapsulating the compound of formula (I), may be prepared in a knownmanner, typically by intimately mixing and/or grinding the compound withextenders, for example solvents, solid carriers and, optionally, surfaceactive compounds (surfactants).

Advantageous rates of application are normally from 5 g to 2 kg ofactive ingredient (a.i.) per hectare (ha), preferably from 10 g to 1 kga.i./ha, most preferably from 20 g to 600 g a.i./ha. When used as seeddrenching agent, convenient dosages are from 10 mg to 1 g of activesubstance per kg of seeds.

When the combinations of the present invention are used for treatingseed, rates of 0.001 to 50 g of a compound of formula I per kg of seed,preferably from 0.01 to 10 g per kg of seed are generally sufficient.

Suitably, a composition comprising a compound of formula (I) accordingto the present invention is applied either preventative, meaning priorto disease development or curative, meaning after disease development.

The compositions of the invention may be employed in any conventionalform, for example in the form of a twin pack, a powder for dry seedtreatment (DS), an emulsion for seed treatment (ES), a flowableconcentrate for seed treatment (FS), a solution for seed treatment (LS),a water dispersible powder for seed treatment (WS), a capsule suspensionfor seed treatment (CF), a gel for seed treatment (GF), an emulsionconcentrate (EC), a suspension concentrate (SC), a suspo-emulsion (SE),a capsule suspension (CS), a water dispersible granule (WG), anemulsifiable granule (EG), an emulsion, water in oil (EO), an emulsion,oil in water (EW), a micro-emulsion (ME), an oil dispersion (OD), an oilmiscible flowable (OF), an oil miscible liquid (OL), a solubleconcentrate (SL), an ultra-low volume suspension (SU), an ultra-lowvolume liquid (UL), a technical concentrate (TK), a dispersibleconcentrate (DC), a wettable powder (WP) or any technically feasibleformulation in combination with agriculturally acceptable adjuvants.

Such compositions may be produced in conventional manner, e.g. by mixingthe active ingredients with appropriate formulation inerts (diluents,solvents, fillers and optionally other formulating ingredients such assurfactants, biocides, anti-freeze, stickers, thickeners and compoundsthat provide adjuvancy effects). Also conventional slow releaseformulations may be employed where long lasting efficacy is intended.Particularly formulations to be applied in spraying forms, such as waterdispersible concentrates (e.g. EC, SC, DC, OD, SE, EW, EO and the like),wettable powders and granules, may contain surfactants such as wettingand dispersing agents and other compounds that provide adjuvancyeffects, e.g. the condensation product of formaldehyde with naphthalenesulphonate, an alkylarylsulphonate, a lignin sulphonate, a fatty alkylsulphate, and ethoxylated alkylphenol and an ethoxylated fatty alcohol.

A seed dressing formulation is applied in a manner known per se to theseeds employing the combination of the invention and a diluent insuitable seed dressing formulation form, e.g. as an aqueous suspensionor in a dry powder form having good adherence to the seeds. Such seeddressing formulations are known in the art. Seed dressing formulationsmay contain the single active ingredients or the combination of activeingredients in encapsulated form, e.g. as slow release capsules ormicrocapsules.

In general, the formulations include from 0.01 to 90% by weight ofactive agent, from 0 to 20% agriculturally acceptable surfactant and 10to 99.99% solid or liquid formulation inerts and adjuvant(s), the activeagent consisting of at least the compound of formula (I) optionallytogether with other active agents, particularly microbiocides orconservatives or the like. Concentrated forms of compositions generallycontain in between about 2 and 80%, preferably between about 5 and 70%by weight of active agent. Application forms of formulation may forexample contain from 0.01 to 20% by weight, preferably from 0.01 to 5%by weight of active agent. Whereas commercial products will preferablybe formulated as concentrates, the end user will normally employ dilutedformulations.

Whereas it is preferred to formulate commercial products asconcentrates, the end user will normally use dilute formulations.

Biological Examples General Examples of Leaf Disk Tests in Well Plates

Leaf disks or leaf segments of various plant species are cut from plantsgrown in a greenhouse. The cut leaf disks or segments are placed inmultiwell plates (24-well format) onto water agar. The leaf disks aresprayed with a test solution before (preventative) or after (curative)inoculation. Compounds to be tested are prepared as DMSO solutions (max.10 mg/ml) which are diluted to the appropriate concentration with 0.025%Tween20 just before spraying. The inoculated leaf disks or segments areincubated under defined conditions (temperature, relative humidity,light, etc.) according to the respective test system. A singleevaluation of disease level is carried out 3 to 14 days afterinoculation, depending on the pathosystem. Percent disease controlrelative to the untreated check leaf disks or segments is thencalculated.

General Examples of Liquid Culture Tests in Well Plates

Mycelia fragments or conidia suspensions of a fungus prepared eitherfreshly from liquid cultures of the fungus or from cryogenic storage,are directly mixed into nutrient broth. DMSO solutions of the testcompound (max. 10 mg/ml) are diluted with 0.025% Tween20 by a factor of50 and 10 μl of this solution is pipetted into a microtiter plate(96-well format). The nutrient broth containing the fungalspores/mycelia fragments is then added to give an end concentration ofthe tested compound. The test plates are incubated in the dark at 24° C.and 96% relative humidity. The inhibition of fungal growth is determinedphotometrically after 2 to 7 days, depending on the pathosystem, andpercent antifungal activity relative to the untreated check iscalculated.

Fungicidal Activity Against Puccinia recondita f. Sp. Tritici/Wheat/LeafDisc Preventative (Brown Rust)

Wheat leaf segments cv. Kanzler were placed on agar in multiwell plates(24-well format) and sprayed with the formulated test compound dilutedin water. The leaf disks were inoculated with a spore suspension of thefungus 1 day after application. The inoculated leaf segments wereincubated at 19° C. and 75% relative humidity (rh) under a light regimeof 12 hours light/12 hours darkness in a climate cabinet and theactivity of a compound was assessed as percent disease control comparedto untreated when an appropriate level of disease damage appears inuntreated check leaf segments (7 to 9 days after application).
